Carbohydrate (CHO) mouth rinsing seems to improve performance in exercises lasting 30-60 min. However, its effects on intermittent exercise are unclear. It is also unknown whether serial CHO mouth rinses can promote additional ergogenic effects when compared with a single mouth rinse. The aim of this study was to evaluate the effect of single and serial CHO mouth rinses on Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR 1) performance in soccer players. In a randomized, crossover, double-blind, placebo-controlled design, 12 male ( 18.9 * 0.5 years) soccer players performed eight serial mouth rinses under three different conditions: placebo solution only (noncaloric juice), seven placebo mouth rinses plus a single CHO mouth rinse (8% maltodextrin), or eight CHO mouth rinses (8-CHO). Following the final mouth rinse, individuals performed the Yo-Yo IR 1 test to evaluate the maximal aerobic endurance performance measured via total distance covered. There were no differences in Yo-Yo IRl performance between sessions (p =.32; single CHO mouth rinse (8% maltodextrin): 1,198 + 289 m, eight CHO mouth rinses: 1,256 + 253 m, placebo: 1,086 * 284 m). In conclusion, single and serial CHO mouth rinsing did not improve performance during the Yo-Yo IRl for soccer players. These data suggest that CHO mouth rinsing is not an effective ergogenic strategy for intermittent exercise performance irrespective of the number of rinses. [ABSTRACT FROM AUTHOR] |
